Objective:
To evaluate the effect of pectoralis major myocutaneous (PMM) flap reconstruction on upper extremity dysfunction.
Methods:
Patients undergoing PMM flap reconstruction following head and neck cancer resection were enrolled. The control group comprised age-, sex- and clinical characteristic-matched patients undergoing non-PMM flap reconstruction. All patients completed the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire preoperatively and >1 year postoperatively.
Results:
There was no significant difference between pre- and postoperative DASH scores in the control group (n = 46; 2.38 ± 3.33 and 2.99 ± 4.21, respectively). In the PMM flap group (n = 46), the postoperative DASH score was significantly higher than the preoperative score (7.00 ± 9.13 and 2.44 ± 3.50, respectively). In the PMM flap group, flap size was significantly associated with postoperative DASH score.
Conclusion:
PMM flap reconstruction has a small but significant negative effect on upper extremity dysfunction.

Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
